So I have the same " service ride control " message as everybody else and it sits low in the back. I would like to keep the original air ride system and was wondering if the problem is most likely just in the back shocks ? Or would I have to change the compressor and other parts of the air ride system as we'll? Am I better off just getting an aftermarket conversion kit ? Any feedback on brands ? Any help appreciated thanks. Also is there a diagram for the air ride system ?
